Cannot upgrade TCL port

it start upgrading Tcl. After compilation, it starts making tests like
the one below. Each test times out after some minutes. It would take a
day to run all the tests. Why they are failing? How can I disable the
tests? The main problem is that there are other packages depending on
TCL, and portupgrade won't upgrade them because TCL fails to upgrade.
Please help.
